Install Unreal Engine from a folder

Hello

I want to install Unreal Engine 4 on my new computer, by I have a very slow connection on this one. Unreal Engine 4.10.2 is already installed on my old laptop, in C:/Program Files/Epic Games. I tried to copy and paste the folder from my old to my new PC, but it didn’t work and the launcher makes me download Unreal Engine 4.10 instead of finding it from the new folder.

Is there a way I can simply copy and paste, and use it this way ? Downloading 4go would take my all my week-end, and I really don’t have time for this. :frowning:

Thank you !

Oh, looks like I can run the game from C:\Program Files (x86)\Epic Games\4.10\Engine\Binaries\Win64\Editor.exe without launching the launcher.
I had to download two differents .dll files tho, and put them in the folder.
